Reducing ophthalmic surgical waste through electronic instructions for use: a multisociety position paper.

Every ophthalmic surgical supply, including intraocular lenses (IOLs), IOL cartridges, and ophthalmic viscosurgical device syringes, is packaged with instructions for use (IFU). These pamphlets are printed in multiple languages and, in the case of an IOL, significantly increase the size and weight of the packaging. To eliminate this significant and unnecessary source of waste, we recommend that manufacturers move to Quick Response codes that link to online electronic IFU (e-IFU) as a sensible alternative. In addition to reducing carbon emissions and manufacturing costs, e-IFU can be updated more easily and accessed by surgeons in the clinic, where IOL models and powers are selected. Varying and inconsistent IFU requirements between different countries are a barrier to wider adoption of e-IFU by the ophthalmic surgical industry. Regulatory agencies in every country should allow and encourage e-IFU. This position paper has been endorsed by the 3 major societies that sponsor EyeSustain, a consortium of global societies dedicated to advancing sustainability in ophthalmology.

A Randomized, Prospective, Observer-Masked Study Comparing Dropless Treatment Regimen Using Intracanalicular Dexamethasone Insert, Intracameral Ketorolac, and Intracameral Moxifloxacin versus Conventional Topical Therapy to Control Postoperative Pain and Inflammation in Cataract Surgery.

Purpose: To evaluate clinical efficacy and patient preference for a dropless treatment regimen compared to conventional topical therapy in patients undergoing cataract surgery. Patients and Methods: In this prospective, contralateral eye study, patients with bilateral cataract were randomized to receive either intracanalicular dexamethasone insert, intracameral phenylephrine 1%/ketorolac 0.3%, and intracameral moxifloxacin (50 µg) (study group) or topical moxifloxacin 0.5%, ketorolac 0.5%, and prednisolone acetate 1.0% QID (control group). The second eye underwent cataract surgery 2 weeks later and was treated with the opposite treatment. All patients were evaluated at Days 1, 7, 14, 28, and 3 months. The primary outcome measure was postoperative ocular pain. Secondary outcomes included summed ocular inflammation score (SOIS; the sum of the mean anterior chamber cells and anterior flare score), the patient preference for medication protocol between the two eyes, and patient out-of-pocket cost of medications. Safety outcome measures included CDVA, intraocular pressure, central retinal thickness (CRT), and the incidence of reported AEs. Results: The proportion of patients with no pain was similar in both groups at all postoperative visits (p>0.05). No statistically significant difference in SOIS score was observed between the two groups at any visit. A strong majority of the patients (94.7%) preferred the study eye's dropless regimen over the control eye's conventional topical therapy regimen. No statistically significant difference in mean intraocular pressure (IOP) was observed at any postoperative visit, except at Week 1. The mean CDVA was also similar in both groups at all postoperative visits (p>0.05). The postoperative mean CRT was comparable between the two groups. Conclusion: A dropless treatment regimen is as effective as topical eyedrop administration. A higher proportion of patients who underwent bilateral cataract surgery preferred the dropless treatment regimen over the patient-administered eye drop regimen.

A Prospective Study of Cyclosporine A 0.1% Combined with Loteprednol 0.2% vs Cyclosporine A 0.05% Alone in the Treatment of Dry Eye.

Purpose: To examine the efficacy and tolerability of a combination of cyclosporine 0.1% and loteprednol 0.2% (CsA-LE; Klarity CL) in comparison to commercially available cyclosporine 0.05% (CsA; Restasis) in improving signs and symptoms of dry eye. Methods: This multicenter, prospective, randomized, controlled, open-label study evaluated 60 patients randomized to a single treatment for 4 weeks and evaluated at day 0, day 14, and day 28. Comparison was made of corneal higher-order aberrations (HOAs), dry-eye symptoms (SPEED score), tear-breakup time (TBUT), corneal staining, and ocular hyperemia, as well as tolerability of each medication with the validated COMTOL instrument. Results: A total of 56 patients completed enrollment. Corneal HOAs improved significantly with CsA-LE, but not CsA alone. Both groups showed significant improvement (with no significant differences between groups) in SPEED scores, corneal staining, TBUT, and conjunctival hyperemia. Tolerability was similar between the drugs, and no significant safety issues were identified. Conclusion: The combination of CsA 0.1%-LE 0.2% provided significant improvement in corneal HOAs, while CsA 0.05% did not. For all other measures of ocular surface improvement, both medications showed similar benefits. Tolerability was comparable between the formulations. When rapid rehabilitation of the ocular surface is needed to reduce aberrations, CsA-LE is an appropriate choice.

Radial keratotomy and cataract surgery: A quest for emmetropia.

A 75-year-old man with an ocular history of 8-cut radial keratotomy (RK) in both eyes presented for cataract surgery evaluation. He was previously correctable in spectacles in years prior despite his irregular corneas to 20/25 in the right eye and 20/30 in the left eye. He recently noticed a change in his overall visual function with significant nighttime glare and difficulty reading despite spectacle correction. Of note, he was unable to tolerate contact lenses and was resistant to refitting despite additional encouragement. Cataract surgery was delayed for many years, given he was correctable in spectacles and the concern of uncovering a highly aberrated cornea after removing his cataracts (Figures 1 and 2JOURNAL/jcrs/04.03/02158034-202308000-00021/figure1/v/2023-07-21T030437Z/r/image-tiffJOURNAL/jcrs/04.03/02158034-202308000-00021/figure2/v/2023-07-21T030437Z/r/image-tiff). Of note, the patient was interested in returning to the spectacle independence he enjoyed in the past. Ocular examination revealed a corrected distance visual acuity (CDVA) of 20/30 in the right eye and 20/60 in the left eye, with a manifest refraction of +4.50 -0.50 × 177 in the right eye and +5.75 -1.75 × 14 in the left eye. Glare testing was 20/50 in the right eye and 20/100 in the left eye, with retinal acuity meter testing of 20/25 in each eye. Pupils, confrontation visual fields, and intraocular pressures were normal. Pertinent slitlamp examination revealed corneal findings of 8-cut RK with nasal-gaping arcuate incisions in both eyes and lens findings of 2+ nuclear sclerosis with 2+ cortical changes in the right eye and 3+ nuclear sclerosis with 3+ cortical changes in the left eye. Cup-to-disc ratios of the optic nerves measured 0.5 with temporal sloping in the right eye and 0.6 with temporal sloping in the left eye. The dilated fundus examination was unremarkable. What intraocular lens (IOL) options would you offer this patient and how would you counsel regarding realistic expectations? What additional diagnostic testing would be helpful in your assessment? How would you calculate the IOLs?

Accuracy of the LaserArcs Femtosecond Cataract Surgery Arcuate Incision Nomogram in Patients Undergoing Cataract Surgery and Astigmatism Reduction.

Purpose: The purpose of this study is to evaluate the efficacy and safety of the laserarcs.com nomogram in reducing astigmatism among cataract patients that underwent astigmatism reduction with laser arcuate incisions. Methods: In this retrospective study, 50 patients who underwent uncomplicated cataract surgery with laser arc incisions for the reduction of astigmatism with a single surgeon between the dates of January 23, 2021 and February 10, 2022 were evaluated in a single eye. Preoperative astigmatism was determined on the basis of keratometry from biometry (IOLmaster, Carl Zeiss Meditec or LenStar LS900, Haag-Streit, Bern, Switzerland) and was compared to the postoperative manifest astigmatism. The percent change in the absolute magnitude of astigmatism was calculated along with the percent of patients with various levels of postoperative astigmatism. Results: Mean cylinder was 0.97 ± 0.49 D pre-op and 0.21 ± 0.28 D postop. Mean reduction in cylinder was 81.4 ± 47.7% (P < 0.00001, one-sample t-test compared to a hypothetical 60% reduction in cylinder). Residual cylinder was ≤0.5 D in 90%, 0.25 D in 72%, and 0 D in 58%. Postoperative uncorrected visual acuity was 20/30 or better in 92% and 20/20 or better in 40%. Subgroup analysis showed that residual astigmatism was not affected by patient age, magnitude of preoperative astigmatism, preoperative spherical equivalent, or corneal curvature. No adverse events related to the laser arcuate incisions were noted. Conclusion: Use of the LaserArcs nomogram yielded a significant reduction in preoperative astigmatism. Postoperative uncorrected visual acuity was substantially similar to best-corrected visual acuity, suggesting that many patients undergoing treatment will function without correction for distance tasks.

Identifying and addressing common contributors to nonadherence with ophthalmic medical therapy.

PURPOSE OF REVIEW: To discuss common reasons for nonadherence and review existing and emerging options to reduce nonadherence with ocular medical therapy and optimize therapeutic outcomes. RECENT FINDINGS: Nonadherence can arise from patient-related issues (e.g. physical, cognitive) and healthcare-related issues (e.g. cost, access to care). Multiple strategies have been developed and evaluated to overcome these barriers to adherence. Identifying nonadherence and its cause(s) facilitates the development of strategies to overcome it. SUMMARY: Many common causes of nonadherence can be mitigated through a variety of strategies presented.

Phase 2, Randomized, Open-Label Parallel-Group Study of Two Dosing Regimens of Netarsudil for the Treatment of Corneal Edema Due to Fuchs Corneal Dystrophy.

Background: This phase 2 study evaluated the therapeutic potential of netarsudil to reduce corneal edema and to improve vision in patients with Fuchs corneal dystrophy (FCD). Methods: Patients (N = 40) with baseline central corneal thickness (CCT) of ≥600 µm and best-corrected visual acuity (BCVA) of 70-20 letters (20/40-20/400 Snellen equivalent) were randomized 1:1 to receive netarsudil once a day (QD) or twice a day (BID) for 8 weeks. Primary endpoint was mean CCT change from baseline at week 4. Results: Netarsudil QD and BID significantly reduced CCT at week 4 [mean change (standard error of mean), 28.4 (7.99) µm, P = 0.0021; and 20.1 (8.75) µm, P = 0.0335, respectively]. Five (12.5%) patients achieved complete resolution of corneal edema at week 4. BCVA improved by 3.2 (2.76) letters with QD and 1.5 (2.84) letters with BID, and 10 (25%) patients [5 with QD (P = 0.0078) and 5 with BID (P = 0.0096)] gained ≥10 letters at week 4. Improvements in CCT and vision were observed at week 2 and persisted at week 8, without significant differences between the 2 doses at any time point. Netarsudil QD significantly improved visual acuity and glare factor scores on the Visual Function and Corneal Health Status (V-FUCHS) questionnaire at weeks 4 and 8 (mean change, -0.4 to -0.3; P ≤ 0.0200). Netarsudil was well tolerated. Reticular edema developed in one (2.5%) patient with BID, which resolved with treatment discontinuation. Conclusions: Netarsudil QD led to significant reductions in corneal edema as well as improvements in vision and patient-reported symptoms of glare and visual impairment in patients with FCD. Clinical Trial Registration Number: NCT04498169.

The DEPOT Study (Dry Eye Prescription Options for Therapy): Assessing the Efficacy and Safety of OTX-DED (Dexamethasone Ophthalmic Insert 0.3 mg) for Intracanalicular Use Compared with Loteprednol Suspension for the Treatment of Episodic Dry Eye.

Purpose: To compare OTX-DED, an investigational dexamethasone intracanalicular insert, to loteprednol 0.5% suspension applied QID for 28 days as treatments for acute exacerbations of dry eye disease in terms of patient symptoms, corneal staining, tear breakup time (TBUT), and ocular redness. Methods: Fifty patients with an acute exacerbation of dry eye with at least grade 1 corneal staining were randomized to receive treatment and were each evaluated in one eye at baseline, two weeks and four weeks with the standard patient evaluation of eye dryness (SPEED) questionnaire, the Oxford Scale for corneal stain, Schulze Scale for ocular redness, and intraocular pressure (IOP). Results: Forty-four patients completed the study. Significant improvement was noted from baseline to both week 2 and 4 for each treatment in SPEED scores, corneal staining, and TBUT. Ocular redness improved significantly from baseline to week 2 for loteprednol and week 4 for both drugs. No significant difference was noted between treatments in any of these evaluations at any time point. Retention (visibility) of the OTX-DED insert was 95% at week 2 and 90% at week 4. IOP rose significantly from baseline to both week 2 and 4 for eyes receiving loteprednol but not for those receiving OTX-DED. Conclusion: OTX-DED significantly improved on both signs and symptoms of eyes suffering from acute exacerbations of dry eye disease. This improvement was similar to that seen with loteprednol 0.5% suspension, a well-accepted treatment for this condition. IOP did not change significantly in patients with OTX-DED. These findings support the use of this unique intracanalicular insert for the treatment of acute dry eye once this product is approved and available for use.

Matrix Metalloproteinase-14 as an Instigator of Fibrosis in Human Pterygium and Its Pharmacological Intervention.

There exists a paucity of information on the pathogenesis of pterygium, a benign ocular tumor that scars the cornea and can lead to vision loss. The main recourse for pterygium is surgery; however, recurrence is observed. Matrix metalloproteinases (MMPs) are involved in the pathology of pterygium. The determination of the specific MMP involved among the 24 human enzymes has not been established due to challenges in MMP profiling. We used an affinity resin that binds specifically to the active forms of MMPs in the complex mixture of the cellular proteome. The proteomics analysis identified active MMP-14 and three related metalloproteinases, ADAM9, ADAM10, and ADAM17, in human pterygia. Inhibition of MMP-14 with the small-molecule inhibitor (R)-ND-336 was assessed in cell migration and collagen contraction assays. (R)-ND-336 attenuated human conjunctiva fibroblast migration and mitigated collagen contraction, both activities required for the formation of pterygium. (R)-ND-336 holds the promise of a therapeutic recourse for pterygium as an orphan disease.

Reduction of Artificial Tears and Use of Adjunctive Dry Eye Therapies After Lifitegrast Treatment: Evidence from Clinical and Real-World Studies.

Purpose: To assess the frequency of patients reducing the use of artificial tears (ATs) among patients with dry eye disease (DED) following lifitegrast treatment. Patients and Methods: Two independent analyses were performed using the data from the 1-year, randomized, multicenter, Phase 3 SONATA trial and a noninterventional, real-world evidence (RWE) study conducted in patients with DED who were treated with lifitegrast in the United States and Canada. In SONATA, patients who had used ATs in the lifitegrast and placebo groups were included. The RWE study reviewed patients' electronic medical records, prescribing patterns, and practices of physicians throughout the survey. These data were then used to compare the proportion of patients using ATs in the 6-month pre-index period versus the 12-month post-index period. Results: Of 293 patients (lifitegrast, n=195; placebo, n=98) from SONATA, 107 (lifitegrast, n=64; placebo, n=43) used ATs during the on-therapy period while 186 (lifitegrast, n=131; placebo, n=55) did not. Of those not using ATs, the proportion of patients in the lifitegrast group at any time was higher (~67% [n=131]) versus placebo (~56% [n=55]); this was the case at all study time-points (Days 90, 180, 270, and 360). The RWE study included 600 patient charts (US, n=550; Canada, n=50); 75.5% (n=453) reported AT use. There was ~40% decrease in the proportion of patients using ATs as adjunct DED therapy to lifitegrast in the post-index period (n=273) versus those in the pre-index period (n=453). Conclusion: The findings show that the reliance on AT use can be gradually reduced with lifitegrast treatment, eventually leading to a reduction in disease burden.

Intracameral dexamethasone 9% vs prednisolone acetate 1% in controlling postoperative pain and inflammation in patients undergoing cataract surgery.

PURPOSE: To compare patient preferences of postoperative cataract surgery topical medication use between a 1-drop and a 3-drop regimen. SETTING: Two private cataract surgery centers. DESIGN: Open-label randomized self-controlled prospective study. METHODS: This study included 30 patients (60 eyes) undergoing routine cataract surgery in both eyes. In this contralateral eye study, 1 eye of each patient was randomized to the 1-drop regimen of intracameral delivery of moxifloxacin and dexamethasone suspension and topical bromfenac for 30 days. The other eye, randomized to the 3-drop regimen, received topical moxifloxacin 0.5% 4 times a day for 7 days and bromfenac 0.07% daily for 30 days postoperatively, along with prednisolone acetate 1% 4 times a day for 30 days. Patients reported their preferred regimen 2 weeks after the second surgery with a validated questionnaire. Secondary outcomes included subjective ocular pain, inflammation score, and out-of-pocket cost. Intraocular pressure (IOP) and macular thickness were also measured. RESULTS: Of the 29 patients, 28 (96.6%) significantly more preferred the eye treated with a 1-drop regimen. Self-reported pain, activity interference, and out-of-pocket cost were significantly less in the 1-drop group. Inflammation and 1-day uncorrected distance visual acuity were also significantly better in the 1-drop group. Macular thickness and mean IOP were similar between groups. CONCLUSIONS: Intracameral delivery of steroid and antibiotics was preferred by most of the patients undergoing cataract surgery. These eyes had significantly less pain, inflammation, activity interference, and out-of-pocket cost and significantly better uncorrected distance visual acuity at 1 day postoperatively. IOP and macular thickness were similar between groups.

The Vivity Extended Range of Vision IOL vs the PanOptix Trifocal, ReStor 2.5 Active Focus and ReStor 3.0 Multifocal Lenses: A Comparison of Patient Satisfaction, Visual Disturbances, and Spectacle Independence.

PURPOSE: To compare patient-reported outcomes (PROs) after intraocular lens (IOL) implantation with the AcrySof IQ Vivity IOL or Vivity Toric IOL to those achieved with other multifocal IOLs. PATIENTS AND METHODS: Prospective, open-label, multicenter analysis of PROs, including spectacle independence, dysphotopsia, and overall satisfaction among patients who underwent cataract surgery at least 1 month previously with bilateral Vivity or Vivity Toric lenses (n=60). Results were compared to outcomes from two similar prospective studies of bilateral AcrySof IQ PanOptix or PanOptix Toric trifocal IOLs (n = 59), blended AcrySof ReSTOR 2.5/3.0 IOLs (n=72) or bilateral ReSTOR ActiveFocus 2.5 D IOLs with a mini-monovision target [n = 95]). RESULTS: Patients in the Vivity cohort were significantly less likely to notice glare and halo in dim light (85% "none" or "just a little") compared to PanOptix (69%, p<0.03), 2.5 mini-monovision (75%, p< 0.05) or 2.5/3.0 (71%, p< 0.05) patients. Complete spectacle independence for all visual activities combined (never need glasses) with Vivity was comparable to the mini-monovision and 2.5/3.0 groups (33%, 36%, and 31%, respectively) but significantly lower than in the PanOptix cohort (83%, p < 0.0001). Satisfaction was high across all groups. There were no statistically significant differences in best-corrected visual acuity, and no new safety concerns were reported. CONCLUSION: The AcrySof IQ Vivity extended depth of focus IOL offers an expanded range of vision and better spectacle independence than has typically been achieved with traditional monofocal IOLs, with high rates of satisfaction and a favorable dysphotopsia profile compared to diffractive multifocal IOLs.

TearCare for the Treatment of Meibomian Gland Dysfunction in Adult Patients With Dry Eye Disease: A Masked Randomized Controlled Trial.

PURPOSE: The aim of this study was to demonstrate the safety and effectiveness of a single TearCare procedure compared with a single LipiFlow procedure in treatment of the dry eye disease associated with meibomian gland dysfunction. METHODS: In a multicenter, masked, randomized controlled trial, 135 subjects received a single TearCare (TC) treatment (n = 67) or a single LipiFlow (LF) treatment (n = 68) at baseline and were followed up for 1 month posttreatment. Tear film breakup time, meibomian gland function, and corneal and conjunctival staining scores were assessed as dry eye signs at baseline, 2 weeks, and 1 month; dry eye symptoms were assessed using the Ocular Surface Disease Index, Symptom Assessment in Dry Eye, and eye dryness questionnaires at baseline and 1 month. RESULTS: At 1 month posttreatment, both groups demonstrated significant improvements (P < 0.0001) in mean tear film breakup time and meibomian gland secretion score to 3.0 ± 4.4 and 11.2 ± 11.1 in the TC group and 2.6 ± 3.3 and 11.0 ± 10.4 in the LF group, respectively. The mean eye dryness, Symptom Assessment in Dry Eye, and Ocular Surface Disease Index scores were significantly reduced (P < 0.0001) by 35.4 ± 34.1, 38.2 ± 31.0, and 27.9 ± 20.5 in the TC group and 34.9 ± 26.9, 38.0 ± 25.9, and 23.4 ± 17.7 in the LF group, respectively. There were no statistically significant differences for any result between the groups. However, the TC group demonstrated numerically greater improvements consistently in all signs and symptoms. Device-related ocular adverse events were reported in 3 patients in the TC group (superficial punctate keratitis, chalazion, and blepharitis) and 4 patients in the LF group (blepharitis, 2 cases of foreign body sensation, and severe eye dryness). CONCLUSIONS: A single TearCare treatment significantly alleviates the signs and symptoms of dry eye disease in patients with meibomian gland dysfunction and is equivalent in its safety and effectiveness profile to LipiFlow treatment as shown in this 1-month follow-up study.

Call to action: treating dry eye disease and setting the foundation for successful surgery.

Dry eye disease (DED) is a common disease that can reduce the quality of life. Prevalence estimates vary but have been reported to be as high as 60% in some populations. Diagnosis is complicated by a multifactorial etiology and a disconnection between clinical signs and patient-reported symptomatology. Critically, preexisting DED can exacerbate postoperative dry eye symptoms and reduce patient satisfaction after ocular surgery, highlighting the value of thorough evaluation and screening for signs and symptoms of DED in preparation for ocular surgery. This article reviewed predisposing and exacerbating factors for DED and presented an argument for the importance of adequately treating DED prior to surgery, from the perspective of both the patient and the provider. It briefly reviewed currently available methodologies and emphasized the utility of multimodal diagnosis and treatment algorithms to optimize outcomes and patient satisfaction.

Meibomian Gland Dysfunction: A Dermatological Perspective on Pathogenesis and Treatment Outlook.

Meibomian glands are modified oil-producing glands that produce meibum and can become dysfunctional and negatively affect the lipid layer in the tear film, resulting in ocular surface diseases such as evaporative dry eye. Abnormal keratin production and aggregation at the meibomian gland orifice has been implicated in the pathogenesis of meibomian gland dysfunction (MGD). Current treatments largely ignore the role of keratin proteins. This review paper synthesizes various publications on hyperkeratinization and its role in MGD pathogenesis and proposes a novel treatment strategy for MGD that involves the use of keratolytic agents commonly used in dermatological treatments.

Effect of Cyclosporine 0.09% Treatment on Accuracy of Preoperative Biometry and Higher Order Aberrations in Dry Eye Patients Undergoing Cataract Surgery.

PURPOSE: To determine the effect of topical cyclosporine 0.09% on ocular surface regularity and the predictive accuracy of preoperative corneal power measurements in patients undergoing cataract surgery. SETTING: Private practice. DESIGN: Open-label, multicenter, prospective study. METHODS: Seventy-five patients (75 eyes) who presented for cataract surgery evaluation with signs of dry eye disease were prescribed topical cyclosporine 0.09% for 28 days BID. Corneal curvature measurements, slit lamp exam, and Standardized Patient Evaluation of Eye Dryness (SPEED) questionnaire were evaluated at the initial and follow-up visits. Cataract surgery occurred 1 to 3 weeks after the second biometry visit. Refraction and corrected distance visual acuity measurements were performed 1-month post-surgery. The primary outcome was the difference in absolute prediction error of 1-month spherical equivalent refractive outcome before and after cyclosporine treatment. Secondary outcomes included the effect of topical cyclosporine 0.09% on ocular surface irregularity. RESULTS: Sixty-four patients completed the study. The absolute prediction error of 1-month spherical equivalent refractive outcome was 0.39 ± 0.30 D vs 0.33 ± 0.25 D (P < 0.03) before and after treatment, respectively. The proportion of eyes that achieved the target refraction was greater based on measurements after topical cyclosporine 0.09% than would have occurred using pre-treatment measurements. CONCLUSION: Cataract surgery patients with dry eye who are prescribed topical cyclosporine 0.09% BID for 28 days pre-surgery showed a statistically significant improvement in the prediction error of the spherical equivalent outcome of surgery. Other measures of dry eye severity showed significant improvements after treatment.

Cataract Surgical Planning Using Online Software vs Traditional Methods: A Time/Motion and Quality of Care Study.

PURPOSE: The objective of this study is to compare two methods of preoperative planning for placement of intraocular implants: traditional paper documentation/electronic scans versus a novel online planning software. The aim was to compare the time required and number of data points manually transcribed with each method and to explore whether differences in surgical accuracy could be identified between the two methods in a small sample of 40 patients. METHODS: In this study, preoperative planning was performed twice for all enrolled patients: once through the traditional method and once using an online planning software system. The total time spent and number of data points manually transferred were recorded for each method. RESULTS: Of the 40 patients enrolled, the mean total surgical planning time was 239 ± 190 seconds for the traditional method vs 63 ± 31 seconds with the online planning software (P<0.00001). The mean number of data points transcribed was 7.2 ± 7.2 for the traditional method vs 0.9 ± 1.7 with the online planning software (P<0.0000001). No statistically significant differences were noted in terms of accuracy of prediction of the spherical equivalent surgical outcome. CONCLUSION: In comparison to traditional methods, a significant reduction in time required for surgical planning and the manual transcription of data points was noted when a comprehensive online surgical planning software was used. This has important implications for the efficiency and likely the safety of surgical planning.

Comparison of Preoperative Measurements with Intraoperative Aberrometry in Predicting Need for Correction in Eyes with Low Astigmatism Undergoing Cataract Surgery.

PURPOSE: To determine whether intraoperative aberrometry during cataract surgery measures higher levels of absolute astigmatism than preoperative biometry readings and which method yields a lower, final level of astigmatism if the two do not agree. PATIENTS AND METHODS: Retrospective record review of all patients who underwent uncomplicated cataract surgery from February 2015 to May 2019 with planned intraoperative aberrometry. Data analysis included preoperative keratometry, total astigmatism as measured by intraoperative aberrometry, intraocular lens model and power used, and postoperative manifest refraction ≥1 month after surgery. The primary outcome measure was the proportion of patients requiring astigmatism correction (≥0.5 D) when measured by preoperative keratometry vs intraoperative aberrometry. Secondary outcomes included postoperative residual astigmatism, where adjusted preoperative astigmatism fell below the 0.5 D threshold for treatment but the intraoperative measurement was ≥0.5 D or ≥1.0 D. RESULTS: A total of 451 patient records were evaluated. Intraoperative aberrometry measured statistically higher levels of mean astigmatism than keratometry (0.86 D vs 0.79 D, respectively; P < 0.0001) and significantly greater astigmatism among patients with 0.5-1.5 D of adjusted preoperative astigmatism (P < 0.0001). Significantly more patients qualified for with-the-rule astigmatism correction when measured by intraoperative aberrometry (n=339; 75%) than by preoperative keratometry alone (n=314; 70%); P < 0.03. This difference did not hold for against-the-rule or oblique astigmatism. For patients whose preoperative biometry astigmatism differed from intraoperative biometry, final postoperative astigmatism was lower when corrected if the adjusted preoperative and intraoperative measurements had a vector difference of <0.5 D, but there was no additional benefit in final astigmatism reduction when the vector difference was ≥0.5 D. CONCLUSION: Using intraoperative biometry readings can produce lower postoperative astigmatism than using preoperative biometry readings, but caution should be used when interpreting intraoperative readings that disagree with preoperative measurements with a vector magnitude of >0.5 D.

Real-World Experience with Lifitegrast Ophthalmic Solution (Xiidra®) in the US and Canada: Retrospective Study of Patient Characteristics, Treatment Patterns, and Clinical Effectiveness in 600 Patients with Dry Eye Disease.

PURPOSE: This study evaluated real-world treatment of dry eye disease (DED) with lifitegrast. PATIENTS AND METHODS: Ophthalmologists and optometrists treating patients with DED were invited to participate through a healthcare provider (HCP)-based panel. HCPs completed a provider survey and contributed data toward a chart review for up to five qualifying patients with DED who initiated lifitegrast ophthalmic solution (index date) between 01/01/2017 (US) or 01/01/2018 (Canada) and 06/30/2019. Patient demographics, treatments, clinical characteristics, and outcomes (ie, severity, signs, symptoms) were collected for the 6-month pre-index period and up to 12-months post-index. RESULTS: For this study, 517 HCPs contributed 600 patient charts. Among 554 and 281 patients with follow-up at 6 and 12-months post-index, 512 (92.4%) and 238 (84.7%) patients had ongoing lifitegrast treatment, respectively. Other DED-related treatments were less frequently used post-index with lifitegrast vs pre-index: over-the-counter artificial tear use (45.2% vs 75.5%), topical corticosteroids (3.8% vs 18.8%), any cyclosporine (3.0% vs 20.5%). At 3-months (n=571) and 12-months (n=320) post-index vs pre-index, fewer patients had eye dryness (47 [8.2%] and 16 [5.0%] vs 525 [87.5%]), blurred vision (28 [4.9%] and 11 [3.4%] vs 346 [57.7%]), ocular burning/stinging (25 [4.4%] and 8 [2.5%] vs 336 [56.0%]), depression (8 [1.4%] and 9 [2.8%] vs 55 [9.2%]), fatigue (4 [0.7%] and 1 [0.3%] vs 82 [13.7%]), and headache (1 [0.2%] and 0 vs 19 [3.2%]). At 3 and 12-months post-index vs pre-index, average corneal staining score was numerically lower (2.7 and 2.0 vs 6.5), and average Schirmer score (10.6 and 10 vs 6.3) and tear film break-up time (7.3 and 8.0 vs 4.8) higher. CONCLUSION: The majority of patients had ongoing lifitegrast treatment 6-months post-index with reduction in overall treatment burden. Improvement in DED signs and symptoms, including QoL impacts, was evident at 3 months and up to 12 months after lifitegrast initiation.

The PanOptix Trifocal IOL vs the ReSTOR 2.5 Active Focus and ReSTOR 3.0-Add Multifocal Lenses: A Study of Patient Satisfaction, Visual Disturbances, and Uncorrected Visual Performance.

PURPOSE: To compare spectacle independence, patient-reported outcomes (PROs), and dysphotopsia after multifocal intraocular lens (IOL) implantation with the AcrySof PanOptix trifocal or the ReSTOR +2.5/3.0 D or ReSTOR +2.5 D mini-monovision multifocal IOL. PATIENTS AND METHODS: Prospective, open-label, multicenter analysis of PROs, spectacle independence, and satisfaction among patients undergoing cataract surgery who had been implanted at least 1 month previously with AcrySof IQ PanOptix or PanOptix Toric trifocal (n = 59) IOLs bilaterally. Results were compared to outcomes from a similar study with the AcrySof ReSTOR 2.5/3.0 or the ReSTOR ActiveFocus 2.5 mini-monovision lens [n = 191]). RESULTS: Spectacle independence was significantly higher in the PanOptix cohort, with 83% of patients "never" needing glasses for any activity versus 36% in the ReSTOR 2.5 mini-monovision and 34% in the ReSTOR 2.5/3.0 cohorts. No significant differences in patient satisfaction rates were reported between the three cohorts. Glare and halo were rated "extremely" noticeable more with the PanOptix (10%) than with the ReSTOR 2.5 mini-monovision (1%) or ReSTOR 2.5/3.0 (3%). BCVA differences were not statistically significant, and no new safety concerns were reported. CONCLUSION: The AcrySof PanOptix trifocal provides significantly greater spectacle independence across all measured activities than the AcrySof ReSTOR multifocal IOLs.
